His theory is that the cod, which weighed upwards of five kilogrammes, mistook the vibrator for a tasty cephalopod.
"Fish eat all kinds of different things," he said. "And the dildo looks like what the fish eat. We have a kind of multi-coloured octopus in Norway, maybe the cod thought this was one of these and ate it."

Nonetheless, he said that it was amazing that such an unusual object was even there for the fish to swallow.
He speculated that the machine, which still had a small motor at one end but no batteries, had been tossed off a boat, perhaps by "a frustrated woman on a cruise" in the Barents Sea.
"The chances of winning the lottery are probably greater," he added. The cod was filleted and given away.
